Searching for observable effects induced by anomalous triangle singularities

TL;DR

This paper explores the anomalous triangle singularity (ATS), its potential observable effects in particle processes, and how to differentiate ATS phenomena from genuine resonance structures.

Contribution

It provides a detailed analysis of ATS impacts on threshold states and proposes methods to distinguish ATS effects from true dynamic poles.

Findings

ATS can significantly influence threshold state observations

Methods to differentiate ATS from genuine poles are discussed

Implications for understanding newly observed states

Abstract

We investigate the anomalous triangle singularity (ATS) and its possible manifestations in various processes. We show that the ATS should have important impact on our understanding of the nature of some newly observed threshold states. Discussions on how to distinguish the ATS phenomena from genuine dynamic pole structures are presented.
